Docker Basics

Prerequisites

For the purpose of this tutorial, I am using a virtual machine running on EXSI 5.5 host. The VM has 2GB of memory, 1 CPU and 60GB of disk. I named the VM Docker2001.The VM is in a DHCP and DNS environment with a docker2001.dfw.ppnet as the FQDN. If you have a bare metal, you can use that also. The VM has Debian Stretch installed on it.

Installation

Login to your server, create a file called docker_install.sh. Copy and paste the script below into the file.

#!/bin/bash
sudo apt-get -y install curl
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo apt-get -y install software-properties-common
sudo apt-get -y install apt-transport-https
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt-get update
apt-cache policy docker-ce
sudo apt-get install -y docker-ce

Save the file and make the file executable and run the script.

sudo chmod +X docker_install.sh
sudo ./docker_install.sh

Check the installation by checking the docker version

ppaul@docker2001:~$ sudo docker --version
Docker version 18.06.1-ce, build e68fc7a
